- Hello,
- This is a notification of unauthorized use of systems or networks.
- The log of TCP port scans is included below for your reference
- (time zone is UTC). To prevent this mail from getting too big in size,
- at most 5 attempts from each attacker IP are included.
- If you regularly collect IP traffic information of your network, you will see
- the IPs listed connected to various TCP ports of my server at the time logged,
- and I suspect that they also connected to TCP ports of many other IPs.
- If a Linux system was at the attacker's IP, you might want to use the
- command "netstat -ntp" to list its active network connections. If there
- is still some suspicious connection, find out what PID/program/user ID they
- belong to. You might find something to help you solve this problem.
- Please notify the victims (owners of those botnet computers) so that they
- can take appropriate action to clean their computers, before even
- more severe incidents, like data leakage, DDoS, and the rumored NSA spying
- through hijacked botnets, arise. This also helps prevent botnets from
- taking up your network bandwidth.
- (time in UTC)=2020-06-30T16:55:39 (attacker's IP)=<SNIP> (IP being scanned)=91^203^192^19 (TCP port being scanned)=1433
